APPARATUS FOR CASTING STEEL- OR OTHER INGOTS.-

SPECIFICATION forming part of Letters Patent No. 506,518, dated October10, 1893.

. Application filed December 3, 1891. Serial No. 413,855. (No model.)

To all whom it may concern.-

Be it known that I, OWEN F. LEIBERT, a citizen of the United States,residing at Bethlehem, county of Northampton, and State of Pennsylvania,have invented a new and use.- fnl Improvement in Apparatus for CastingSteel and other Ingots and other Shapes, which improvement is fully setforth in the following specification and accompanying drawings.

My invention consists of means hereinafter described for subjectingmolten metal in the formation of ingots, &c., to the action of a heatingmedium injected or otherwise directed upon the top thereof, wherebysegregation of the same and other objectionable features are prevented.

Figure 1 represents a vertical section of an ingot mold embodying myinvention. Fig. 2 represents a horizontal section thereof on line at,ac, Fig. 1. Fig. 3 represents a partial vertical section and partialside elevation of a modification thereof. Fig. at represents a verticalsection of a portion of Fig. 3, on an enlarged scale. Fig. 5 representsa partial vertical section and partial side elevation of anothermodification. Fig. 6 represents a vertical section of another form of aningot mold, the top of which is similar to that shown in Fig. 5. Fig. 7represents a horizontal section on line y, y, Fig. 6. Fig. 8 representsa horizontal section on line z, .2, Fig. 6, on an enlarged scale.

Similar letters ofreference indicate corresponding parts in the severalfigures.

Referring to the drawings:A designates an ingot mold, B designates asink-head, and B designates the furnace above said head.

0 designates an injector which is located within the flue O, and adaptedfor directing air, steam, gas, &c., into said head, said injector beingprovided with a valve D at the lower end thereof, whereby by means of ascrew-rod E, the volume and pressure of air, and other material ormaterials of combustion, admitted into the head, may be adjusted.

Connected with the flue is a flexible pipe E, the same being adapted toadmit gas or other vapor into said fine, it being noticed that thesupply pipe F of theinjector is also flexible, owing to the necessity ofraising and laterally moving the mold and superimposed head, when theingot is to be removed.

In Figs. 3 and 4, I show an injector C for oil, air, &c., the same beingsupported on the furnace B, by means of legs B An oil receptacle G hasan air pipe H leading thereinto, and an oil discharge pipe J leadingtherefrom, said pipe J being connected with the inj ector, with which isalso connected an air pipe K. The oil escapes from the injector at thelower end,where the air is impacted thereagainst, thus atomizing the oiland directing it in the form of vaporinto the sink-head.

In Fig. 5, I show an injector O which depends within the top of afurnace L, the latter being shown more fully in Fig. 6, said furnacebeing supported upon the sink-head B, and the latter surrounded bysegmental bands L, the ends of which are provided with flanges L throughwhich are passed the bolts M, between which and the heads or nutsthereof are springs N, whereby the bands are permitted to expand andafterward return to their normal'positions.

It will be seen that natural or artificial gas, liquid fuel orcombustible vapor under pressure or natural draft may be injected intothe furnace and directedupon the top of the ingot, so that while theingot is cooling from below, the cooling will be accomplished slowly,and gradually allow slag and other impurities to rise to the top. Now asthe heat 'is directed upon the top of the ingot,-the

latter is kept in a molten condition at said top, whereby the carbon,silicon, manganese, &c., are oxidized, thus preventing the segregationof the metal of the ingot, the ingot being comparatively uniform orsolid throughout, and divested of piping which is otherwise a seriousdetriment to heavy castings or ingots.

For long or wide plates or ingots, I may use numerous injectors. Whendesired, the molten steel or other metal in the mold may be covered withslag or other material, the'same serving as a blanket.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. An ingot mold having a removable sink head, a furnace on said head, aflue leading into said furnace, a fuel injector in said flue having avalve atits lower end, a flexible supply pipe connected with saidinjector, and a flexible inlet pipe connected with said flue, said partsbeing combined substantially as described.

2. An ingot mold having a sink head, a furnace on said head, a flueleading to said furnace, a fuel injector in said flue having a valve, aflexible supply pipe connected with said injector, and a flexible supplypipe connected with said flue, said parts being combined substantiallyas described.

3. An ingot mold having a sink head, a furnace on said head havingreinforce segmental bands adjustable thereon, a flue on said fur- OWENF. LE'IBERT.
